Hello!

I've a mp4 movie and tried to demux using mp4box+yamb+mp4ui, video and audio, demuxed perfectly but the subtitles i can't demux.
Says not an 3gpp compliant text file.

Please a little help about this subject.

Regards

You may have better luck searching the Doom9 forum and or asking some questions there.

Can you post the output from "MP4Box -info yourFile.mp4".
Are you sure the SUBs are timed text? They are probably VOBSUB.
VOBSUB in mp4 was introduced by Nero.

This is what appears in the info file:

This mp4 file was created with Nero. Both SUB Tracks(6/7) are VOBSUB with a private ObjectTypeIndication.
I don't know a tool to extract this Tracks.

Maybe an other person can help.

hey, i just found this: AutoAC @doom9 forum

what does your tool do with vobsubs exactly?

It gives an option to select which subtitles you want to rip from the source, then outputs *.idx and *.sub files(http://rapidshare.de/files/833344/AutoACsub.gif.html), there is also an option to include vobsub filesize in the output calculations.
Trying to find a way to mux them now.

The post is from a year ago, there might be more info in the rest of the thread.

[rant]If only people stopped using rapidshare... I hate having to reset my IP - wait 40sec - enter captcha all the time. Can't be so hard to get a few megs of free webspace![/rant]

From Vobsub (idx+sub) to srt, use Subrip... but you probably know that.

The only problem is that the program only accepts dvd .ifo files, not other extensions

But thx anyway for your help!
